The sampling variability and zeta-values of parameter estimates for misspecified structural equation models were examined. A Monte Carlo study was used. Results are discussed in terms of asymptotic theory and the implications for the practice of structural equation models. (SLD)

Composite reliability and standard errors of measurement were computed for prorated Verbal, Performance, and Full-Scale intelligence quotient (IQ) scores from a seven-subtest short form of the Wechsler Adult Intelligence Scale-Revised. Results with 1,880 adults (standardization sample) indicate that this form is as reliable as the complete test.…

Comparison of responses to items pertaining to educational attainment on the Current Population Survey before and after 1992 found that the old (pre-1992) items led to more consistent measurement of precollege-level educational attainment. However, use of the old items leads to many errors in attributing degrees to individuals. (JOW)

Presents general principles for cleaning data sets. Suggests techniques: check for column shifts, data completeness, marginal frequencies, and selected cross-tabulations; examines a sample of cases. Gives strategies for preventing data processing errors. (SK)

Analyzed for examiner errors 55 Wide Range Achievement Test-Revised (WRAT-R) protocols completed by 9 practitioners for metropolitan school district. All practitioners made errors, which occurred on 95 percent of protocols and averaged 3.0 errors per protocol. Most frequent errors included failures to obtain correct ceiling or basal, and failures…

A numerical approach for computing standard errors (SEs) of a linear equating is described in which first partial derivatives of equating functions needed to compute SEs are derived numerically. Numerical and analytical approaches are compared using the Tucker equating method. SEs derived numerically are found indistinguishable from SEs derived…

In a previous issue, Lawrence Schweinhart and David Weikart conclude that children who attended a direct-instruction preschool program had significantly greater adult felony arrests than children following the High/Scope or nursery-school curricula. Analysis of research methods suggests improbable links between preschool experience and adult…

Studied whether moving average or autoregressive moving average models fit two longitudinal data sets previously thought to possess quasi-simplex structures better than the quasi-simplex, one-factor, or autoregressive models. Results of a Monte Carlo study show the importance of evaluating the fit, propriety, and parsimony of models before one…

Uses data from two different medical examinations to study how to collect enough information about candidates with minimal measurement error and reasonable confidence without asking examiners for redundant ratings. Results, using the FACETS program show the feasibility of using analytic ratings of clinical skills rather than holistic ratings. (SLD)

Restrictions due to loss of freedom in estimation, the targeting of the instrument, and the presence of misfit in the data were studied through simulation as factors that influence the asymptotic standard errors for person measures. The underestimation of the observed standard deviation of ability in simulated data is discussed. (SLD)

The use of structural equation modeling (SEM) with latent variables to address measurement error and to examine processes that may account for changes in observed outcomes in data from experimental studies is illustrated. An example from a Project Family study is provided; issues that arise in applying SEM procedures are discussed. (Author/EMK)

Classical test theory is founded on the proposition that measurement error, a random latent variable, is a component of the observed score random variable. This article traces the history of the development of classical test theory, beginning in the early 20th century. (SLD)

The Social Relations model of D. A. Kenny estimates variances and covariances from a round-robin of two-person interactions. This paper presents a matrix formulation of the Social Relations model, using the formulation to derive exact and estimated standard errors for round-robin estimates of Social Relations parameters. (SLD)

A research review supports the validity of the person-environment fit (PEF) model in vocational psychology; however, sampling inadequacies have influenced results. One PEF example, Holland's hexagonal model, is unsupported due to lack of commensurate measurement; most hexagonal congruence indices are invalid. (Contains 110 references.) (SK)
